NEW YORK, Jul 24 (Reuters Health) - Chewing gum sweetened with
xylitol can help keep cavities away, US researchers report.
Investigators at the University of Minnesota School of Dentistry found that
chewing gum containing xylitol, an extract from the bark of birch trees, for at
least 5 minutes after meals can suppress the growth of harmful bacteria that
cause cavities. The finding, published in the July 2000 issue of the Journal of
the American Dental Association, offers new treatment possibilities for people
with recurring cavities.
The chief cause of cavities is the bacterium Streptococcus mutans, said lead
researcher Dr. Gary Hildebrandt. "It's at least responsible for initiating
the cavities. Other organisms take over once it gets started," he told
For people who have problems fending off cavities despite cutting down on
sweets and using fluoride products, attacking the bacteria that start the cavity
could help, Hildebrandt said. Antimicrobial rinses kill the bugs, but their
numbers can bounce back within hours.
"We wondered if once we suppressed those organisms...we could keep them
down," Hildebrandt said. "The xylitol gum has been around for a while,
and I had the idea that maybe this would be a good method to keep these
Hildebrandt had 151 people with elevated levels of the bacteria rinse twice a
day for 2 weeks with an antimicrobial mouthwash, called chlorhexidine. The test
subjects were then divided into three groups of about 50 each. One group chewed
the xylitol gum for at least 5 minutes after meals; the second chewed a regular
sugar-free gum (usually sweetened with sorbitol), and the last group did
After 3 months, "we found that the xylitol group was the only group that
the organisms stayed suppressed; the numbers stayed low compared to where they
started (after the mouthwash)," Hildebrandt said.
To be effective, the gum has to have xylitol as its sole sweetener,
Hildebrandt said. Many brands of gum may contain xylitol in addition to other
sweeteners. "The only gums that have 100% xylitol are something you have to
mail order," he said, and usually that means ordering in bulk.
Hildebrandt hopes that this type of product will become generally available
in the future. "Maybe if enough people are asking about it, gum companies
will get the hint."

Xylitol is a sweet-tasting substance
found in small quantities in some berries. Scandinavian research has
found that xylitol can reduce tooth decay, but itís tough to find
products containing xylitol in the U.S. You need to chew one or two
sticks of the gum for five minutes three times a day after meals.
Studies show that this program can reduce tooth decay up to 62%! If

is the result of about twenty years research by Prof Eric Reynolds of
the Univ. of Melbourne. The active ingredients are CPP-ACP.
CPP is casein phosphate peptide (CaPO4 bonded to casein) and ACP is
amorphous calcium phosphate. It supplies very high concentrations
of Ca++ and PO4-- close to the remineralsing tooth in the presence of
high F-. The resultant remineralised hydroxyapatite is of a higher
quality than the normal remineralised hydroxyapatite.Used four times a
day it can reverse white lesions associated with ortho bands in a few
weeks. It is available as an oral cream (Tooth Mousse), a chewing
gum or as mint candy....Trident White in U.S.
